COMMUNICATION SYSTEM, CHARGING CONTROL DEVICE, VEHICLE AND POWER SUPPLY DEVICE

摘要

A communication system, a charging control device, a vehicle, and a power supply device are provided, which prevent noise from flowing into a communication device which transmits and receives a communication signal, in communication such as inband communication in which the vehicle and the power supply device are connected via a charging cable containing a power supply line, a grounding line, and a control line, and the communication signal is transmitted and received by using the grounding line and the control line as media. There are provided: a charging control device connected to a grounding line and a control line, and configured to transmit and receive a control signal; a communication device connected to two branch lines branched from the grounding line and the control line, respectively; and a common mode choke coil interposed in the grounding line and the control line, and located between the charging control device and two branch lines.

1. A communication system in which a control line for transmitting a control signal used for control of charging of an object to be charged and a reference potential line connected to a reference potential are used as media, and a communication signal different from the control signal is transmitted via the media to perform communication, the communication system comprising:
a charging control device connected to the control line and the reference potential line, and configured to control charging in accordance with the control signal; a communication device connected to two branch lines branched from the control line and the reference potential line, respectively, and configured to perform communication by the communication signal; and a pair of induction elements interposed in the control line and the reference potential line.
